Man only likes to count his troubles; he doesn't calculate his happiness.

And therefore the idea of serving mankind, of the brotherhood and oneness of people, is fading more and more in the world, and indeed the idea now even meets with mockery, for how can one drop one's habits, where will this slave go now that he is so accustomed to satisfying the innumerable needs he himself has invented? He is isolated, and what does he care about the whole? They have succeeded in amassing more and more things, but have less and less joy.

Oh, how unbearable is a happy person sometimes!

and what shall I have to dream of when I have been so happy in reality beside you!

And man has actually invented God. And what’s strange, what would be marvellous, is not that God should really exist; the marvel is that such an idea, the idea of the necessity of God, could enter the head of such a savage, vicious beast as man.

There are... things which a man is afraid to tell even to himself, and every decent man has a number of such things stored away in his mind.
